Filling operation steps of dimethyl ether pump

Today, the editor will take you to understand the loading and unloading of dimethyl ether, which has multiple uses in the pharmaceutical, chemical, and pesticide industries. Dimethyl ether is a flammable gas with a certain degree of danger, so special attention should be paid during the filling operation using a dimethyl ether pump. The specific steps are as follows:
1. Before starting to fill bottles or tank trucks, all pump motors should be checked for normal rotation, lubricating oil should be added according to regulations, and the main engine should be running normally.
2. Open the corresponding liquid phase outlet valve and liquid phase return valve at the bottom of the storage tank (tank) according to the required variety for bottling or filling tank trucks.
3. Open the outlet valve of one pump in the liquid phase dimethyl ether pump group.
4. Before the initial bottle filling, open the bottom bottle filling gun valve in the corresponding bottle filling gun group. Start the dimethyl ether pump and slightly open the inlet valve of the pump, adjust the pump to the normal range (if the outlet pressure is high, adjust the reflux valve to control this pressure), exhaust the remaining air in the pipeline, and close the valve of the bottom filling bottle gun when there is a noticeable smell of dimethyl ether at the mouth of the bottom filling bottle gun. Close the dimethyl ether pump and inlet and outlet valves.
5. After connecting the exhausted steel cylinder with the filling gun, start the dimethyl ether pump and slightly open the inlet valve. Adjust the pump to the normal range (if the outlet pressure is high, adjust the reflux valve to control this pressure), and fill to the specified weight.
6. The method of filling tank trucks is basically the same as that of filling bottles, with the difference being that there is one loading port for fine and coarse methyl ether each.
The above are the steps for using a dimethyl ether pump for filling operation. I believe you have gained a certain understanding after reading it, and I hope it can help you. Due to the particularity of dimethyl ether, safety precautions should be taken during operation.
